Power looks great! But man its super lean! that AFR needs to come down to at least 12.8-12.9

 

Sounds like you'll have to do the custom route if you want longtubes. Still, should be well worth the investment, especially if doing a cam.

 

thanks, but is a maf tuning problem... im going the sd way after the cam

i will put a turbo in it so i will leave the stock manifolds, i did this thread so everyone can see the gains a ls9 can do on a stock engine, because i didn´t find one on a stocker just on boosted one´s

just had a trouble with my shipping but i hope i have my cam next week and i´ll post the results... hoping for a 30rwhp gains and 20tq

 

buen trabajo...Me gusta!

 

i installed it and it feels really smooth even more than the stock cam...

i havent drive it yet...

here´s the video of the first start...

lq4 with ls9 cam first start - YouTube



i hope i could take it to the dyno on saturday and i´ll post you if it is a win or a fail...

 

It sounds really good. I'm in for numbers.

 

In for results also...so only change was ls9 cam right?

Sorry if i missed it but what intake manifold are you running?

 

yes, only cam and psi valve springs , i´ll run it with out tune and with a light tune later and see the results... my intake manifold is stock just a 80mm bbk TB but it already had it

 

Are you using a wideband?
wondering how lean its gonna be with the new cam without adjusing the tune.
